lneansol apuinp operating arm `10 which is pivotally connected at 11 to a spoke engaging and embracing clip "12 `which may i be readily applied to any Spoke" of the 'Wheel adjusted longitudinally thereof and held in place thereon. by means of `a clamping ele- `ment 13. The arm 10 is` ofeullicientdengtli to extend `a considerable distance beyond the tread of the Wheel Where it is 'provided with a ground contacting roller 14 journaled `on the extremity of the arm or lever 10 so at so avoid any possibility of the eX- tremity of said arm catching in the ground and demolishing the pump. The arm or lever, 1() is oll'set so as -to carry the wheel clear of the mud guard and said arm or vlever 10 is pivotallyconnected at 15 to the extremity of the piston rod 2 by means of a pivot which is shown in the form o'l a bolt that may be detached for the purpose of disconnectingthe arm or lever 1() from the piston rod 2. The flexible tube 5:3 is also con neoted detachably at 1G to ,the cylinder 1 pt the pump. In this way the lsaid parts of the pump as a whole may be disconnected so as to provide for the compact storage of the same in the machine or vehicle.

From the foregoiiugl description it will non' be understorul,thatas the vehicle Wheel. 5 revolvess, in each revolution thereof the Wheel. 1li comes in contact 'with the ground and is thrust inwardly within the circumt'erev/e of the wheel, after which the arm or le 'er 10 is thrown outward by 'means of a Spring 1(..which is shown as encircling the pistol rod 2, said spring being compressie/d. when thearm or lever 1() is thrust inward. ln this way the pump piston is reciprocated y once .ineach revolution ol the vehicle wheel 1 and `in a `Short time the tire will -bc inflated.

eal'e the wheel '.lflat either .side o'l the longitudinal axis ol the pump cylinder l.

The pump hereinabove deeeribcd is es pcrially useful iu connection with tires huv ingr what is known as a slow leak, the pump serving' to `keep the tire inflated ,until a re pair place is reached.

The iiexible tube 3 provides for the at one en'd beyondthe tread of the Wheel 5 adjustment of the cylinder supporting clip so as to contact With the ground, a clpadto any point throughout the length of the justable longitudinallj9 of one of the spokes' spoke to which it is attached. and radially of the wheel .and to which the What is claimed is An automatic tire inflating pump comprisand a ground Wheel journaled on the outer 10 ing a cylinder and piston pump proper, a end of said lever.
